I recently learned that my boyfriend's father has HD. His grandfather and aunt also had died from the disease. I'm very concerned, because he has a 50% chance of having the illness himself. I'm afraid he may be experiencing some of the early symptoms. He becomes angry easily and has become forgetful and quick to fight. His sister has tested negative and his brother postive. He's 24 years old and intelligent and diligent. He doesn't like talking about it so it's hard for me to bring it up. I'm not sure if it's just his temper or the disease affecting him.
Is there a way for me to identify the symptoms on my own and then steps I can take to help him?
